ABSTRACT: Native microbes in gastrointestinal tract of fish have positive roles due to exogenous enzymes such as amylase. These enzymes promote and support fish endogenous enzymes in hydrolyzing nutrients from fish diet. This research aimed to isolated and selected of probiotic amylolitc bacteria in gastrointestinal tract of gauramy. Selection of probiotic consisted 5 tests namely: Testing Activities amylolytik, Tests for antagonistic activity, resistance to gastric acid and bile salts, attachment test, test of pathogenicity. The selected amylolytic bacteria were: Np 6, Np 7 and Np 8. Bacterial isolates were selected as candidate probiotic bacteria amylolytic bacterial isolates Np 8 because it has a large amylolytic of 18 mm, to survive well at low pH and high pH, has the greatest antagonistic activity against pathogenic bacteria of 9.22 ± 0 , 00 mm in Aeromonas hydrophila.
